IMPROVEMENT IN CAReCOUPLINGS.

Specification forming part of Letters Patent No. 207,094, dated August 1.?, 1878 5 application filed June 2l, 1878.

To all 'whom it may concern:

Be it known that I, JOHN BALLARD, of Cohoes, in the county of Albany and State of New York, have invented certain new and useful Improvements in Gar-Couplings; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a pa-rt of this specication.

This invention relates to car-couplin gs wherein the draw-bar is hinged to the stock and moves sidewise for coupling or uncoupling,'

and which has a double-barbed end, all of which will be hereinafter more fullydescribed.

Figure l is an under-side view, partly in section. Fig. 2 is an end View, showin g the windlass. Fig. 3 is a side view of the draw-bar and partial section.

A is the draw-bar, having the end A' doublebarbed. The draw-bar A is attached, by a hinge-joint, a, to the stock B of a cappiece, B', which has extending from the opposite side a long bolt, B", with a screw-thread and nut at the end; also a iiange, b, on each side of the bolt, near the end of the cap.

The screw-bolt B" passes through two serrated india-rubber springs, C C', which are placed within a frame, D, of H form, the middle bar, d, serving as an abutment on the side next to the draw-bar for an abutment of the springs O C' in either'direction.

At the screw end of bolt B" is a cap-piece, E, having flanges e e to correspond with flanges b b on cap-piece B'. These ilanges work easily outside of the frame D to serve as guides for the movement of the cap-pieces B and E.

The springs O C' are dent-ated on all sides, to admit of easier compression. The nut e' is for giving the proper tension to the sprin gs.

F is a guide, through which the stock B passes. G is a yoke coveringthe side springs M M, which are riveted to its sides f f.l H is Valso a yoke, to keep` the draw-bar A in place. I is a loop or eye, by which the cords or chains K K' are fastened to the draw-bar A. L is the windlass, supported in a frame secured to the car on one side at the end, and L' is a pulley on the opposite side, on a line with the the windlass, supported in standards orpulleybox. M M are hat springs, riveted to the yoke G at ff. The ends of springs M M at m m, where they bear upon the sides of drawbar A, are slightly curved. The other ends bear upon the outside of the guide F at m' m'.

The cord or chain K passes from the loop I around the windlass L, to which it is fastened. The cord K' passes from the loop I over the top, around the pulley L', and under the drawbar A to the windlass L, and is fastened also to it. By turning the hand-wheel L" the draw-bar will be moved in either direction for uncoupling it from the connection.

I claiml. The arrow-headed spring-acted draw-bar A, swiveled to the stock B, having cross-head B', in combination with the crosshead E and the box D, inelosing the springs G and C', which encircle the bolt B", substantially as and for the purpose described.

2. The Vcombination of the windlass L, the two cords K K', pulley AL', and draw-bar A, substantially as and for the purpose described.

3. The combination of the draw bar A, springs M M, springs C C', inclosed in the box B, the cross-heads B' and E,the windlass L, cords KK', and pulley L', all substantially as and for the purpose described.

In testimony thatI claim the foregoing as my own I hereby affix my si gnature in presence of two witnesses.

JOHN BALLARD.
